My second toe had a blister. I wish I could post a picture but it is really nasty looking. It is the tip of the second toe looks like it had blistered and bleed under the skin and now it is black, not as a bruised black but more like a blood cloth. It doesn’t hurt or bother but looks really bad and in the last 1 week it didn’t improve at all. What to do? Should I leave it as it is or put some neosprin on?
